I use these for high power flash guns, portable DAB radio, digitial recording devices and anything that requires batteries to be virtually new for the equipment to work at it's best. The 'life' of the battery is not as good as a top one off the shelf but the re-charge speed is fast (an hour max) and the economics speak for itself. The only down-sides are the charger is pretty bulky if travelling, slower to charge on lower voltage through an adaptor(that is to be expected)and when not used they discharge quicker than normal. Have a few spare sets available to always keep going otherwise there is the hour wait.
